How Vote By Mail Works in Montana

Voting by mail is a two-step process in Montana.

Step 1: Request your ballot NOW! The deadline for your application to be received is November 7th at 12:00 p.m.

Step 2: Complete and return your ballot ASAP

  • Return your ballot in person to local elections office, county designated dropbox, or polling place by November 8th at 8 p.m.
  • Or mail your ballot to your local elections office so that it is received by November 8th. We recommend mailing your ballot at least two weeks before as the post office is not always reliable. The best intentions or postmark will not matter if your ballot is received after November 8th - your ballot will not count.

Where to Sign Your Ballot

Remember to sign your return ballot.

After you fill out your ballot, sign the affidavit on your return envelope.

Be sure that your signature matches your signature on file with the state! If you registered online or at the DMV, check the signature on your license. If the signature does not match, your ballot could be tossed and will not count.

How You Can Return Your Mail-in Ballot

If you return your ballot by mail, you must add a stamp when mailing in your ballot.

You can also drop off your ballot in person at your local elections office, drop box, or polling place.

Can Someone Else Return Your Ballot For You?

An election official, caregiver, family member, household member or acquaintance can return a ballot on your behalf.

Haven't used your ballot?

If you have an absentee ballot that you are not going to use, or you miss the deadline to return, you may go to your polling place and vote in person. If possible, bring your absentee ballot with you. You may be asked to use a provisional ballot. Which is better than not voting, but may not be counted.

Opportunities to Fix Challenges to Your Ballot

Montana does offer voters a chance to address challenges to their ballot.

Your state has a cure period, which means you can “cure” a challenge to the signature on your ballot if it was done incorrectly. Your local elections office is required to contact you and give you options to remedy your ballot. You have until 8 p.m. on Election Day to cure your signature.

You may get a call from a number you do not recognize with a notification that you need to cure your ballot. Be sure to answer so you don’t miss your chance to make sure your vote is counted.

In Montana, you can preregister to vote if you are 18 by the next election. Register to vote today!

Some states even let you vote in their primaries at 17 if you’ll be 18 by the general election so you can participate in the whole process!

You can not vote in the Montana primaries if you are 17 by the next election.
